Answer:
b=6
Step-by-step explanation:
9/b=21/14
9/b=3/2
9=3/2b
9=3b/2
9×2=3b
18=3b
18/3=b
6=b
b=6
Is BC=2.3 one of the options?
For that question, you can use the cosine rule, where;
In this case, we have..
Solving for BC with this will get you 2.250406, rounded off to the tenth is 2.3.
I think it’s 57 bc it is a 90* angle and a 33 so that minus 180
The relation between the two angles ∠a and ∠b is that they are complementary angles. The correct option is B.
<h3>What are complementary angles?</h3>
The angles when added give the sum of 90 degrees and are called complementary angles. The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
In the given figure it is observed that the two angles ∠a and ∠b when added give 90 degrees.
Therefore, the relation between the two angles ∠a and ∠b is that they are complementary angles. The correct option is B.

Answer:
x = 80
y = 100
Step-by-step explanation:
180-80 = 100
Use knowledge on transversals to plug in the 80 and 100 throughout the transversal diagram.
